INTERNAL GRINDING MACHINE IGU 400 CNC

HIGH PRECISION CNC INTERNAL GRINDING MACHINE IGU, UP TO 4 SPINDLES

  • High Precision Internal Grinding machine
  • Up to 4 grinding spindles on the rotating turret
  • Motor controlled by CNC and software interpolation 2-axis allow the adjustment of various rays, customized to the needs of the customer
  • Roller linear guides
  • Axis movement by means of high precision re-circulating ball screw
  • Granite base

Up to 4 grinding spindles on Rotating Turret

An important component of the Internal Grinding Machine IGU 400 is represented by the spindle turret that, in the maximum configuration, can be equipped with:

  • 4 spindles (one of which for external)
  • 4-spindles for internal grinding
  • tailstock to facilitate the grinding bore centering

The tower has an integrated swivel axis that runs automatically and allows you to use up to 4grinding spindles.
The rotation of the turret is automatic and the positioning is accurate and precise ( the turret do not rotates in the versions numer 1 and 2)
